Description
Technical Field
The invention belongs to the technical field of sewage purification, and relates to a water body purification method.
Background
Currently, sewage can be defined as a waste-laden liquid or water mixed with ground water, surface water, storm snow, etc. discharged from residential, institutional, commercial or industrial areas from the viewpoint of the source of the sewage. Sewage is classified into many categories, and there are many techniques and processes for reducing the environmental impact of sewage accordingly. Among water pollution caused by human production activities, water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components, and is not only difficult to purify in water, but also difficult to treat. Domestic sewage, livestock and poultry farm sewage, and wastewater discharged from tanning, wool washing, slaughtering, hospitals, and the like often contain various pathogens, such as viruses, germs, and parasites. Moreover, the sewage has bad smell and serious damage to the environment, and the reuse and treatment of the water quality are far from the priority.

The technical scheme adopted by the invention is a water body purification method, which is implemented by the following steps:
step 1, deodorizing and removing impurities;
step 2, removing heavy metal ions from the water quality subjected to deodorization and impurity removal in the step 1;
step 3, desalting and desalting the water treated in the step 2;
and 4, collecting the water treated in the step 3.
The invention is also characterized in that:
wherein the deodorization process in the step 1 is as follows: introducing chlorine into the water, and adding NaClO in the process of introducing the chlorine;
wherein the impurity removal process in the step 1 is as follows: adding activated carbon for adsorption after water quality deodorization, then fishing out the activated carbon, and adding a coagulant for precipitation;
wherein the process of removing heavy metal ions in the step 2 is as follows: adding an oxidant to oxidize the water, wherein the oxidant is hydrogen peroxide;
wherein the desalting and desalting process in the step 3 comprises the following steps: desalting and desalting water by adopting an electrodialysis method;
wherein the water quality collection process in the step 4 is as follows: atomizing the water treated in the step (3) by using an atomizer, then arranging a filter wall, and spraying the atomized water onto the filter wall for final filtration;
wherein the filter wall includes the filter screen, and the cotton layer that distributes on the filter screen sets up the collecting pit below the filter wall and collects.
The invention has the beneficial effects that:
according to the water body purification method, the water body is purified through multiple impurity removal processes, the water body is purified in all directions, deodorization and impurity removal are performed through a simple and easy-to-operate method, the water body is filtered again through atomization, and the water is filtered and collected through the filter wall, so that the thorough purification of the water quality is guaranteed.
Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The invention provides a water body purification method, which is implemented by the following steps:
step 1, deodorization and impurity removal:
the deodorization process comprises the following steps: introducing chlorine into the water, and adding NaClO in the process of introducing the chlorine;
the impurity removal process comprises the following steps: adding activated carbon for adsorption after water quality deodorization, then fishing out the activated carbon, and adding a coagulant for precipitation;
step 2, removing heavy metal ions from the water subjected to deodorization and impurity removal in the step 1, adding an oxidant to oxidize the water, wherein the oxidant is hydrogen peroxide;
step 3, desalting and desalting the water treated in the step 2, and desalting the water quality by adopting an electrodialysis method, wherein the electrodialysis method is a desalting process for separating anions/cations in the water under the action of an external electric field by utilizing the characteristic that anion/cation exchange membranes can respectively permeate the anions/cations to achieve the water quality;
and 4, collecting the water treated in the step 3: atomizing the water treated in the step (3) by using an atomizer, then arranging a filter wall, and spraying the atomized water onto the filter wall for final filtration; wherein the filter wall includes the filter screen, and the cotton layer that distributes on the filter screen sets up the collecting pit below the filter wall and collects.
The method has simple process operation, organic sulfur, organic amine and other substances in the ozone water are oxidized into compounds with light odor or high solubility by chlorine, then acid and alkali are used for absorption and purification, coagulant is multiple and diverse, alum is generally adopted, the price is low and easy to obtain, the coagulation effect is good, heavy metal ions in the water are subjected to oxidation reduction by hydrogen peroxide, no other byproducts are generated, finally the water is atomized in the atomization process, the water mist is naturally cooled and absorbed by cotton cloth, and then naturally falls down and is collected after being cooled, so that the water quality is clearer and cleaner.
